Gilroy - A road flare manufacturer has reinstated free shipments of
bottled water to 42 homes in Morgan Hill and San Martin after
discovering elevated levels of contaminants in drinking water supplies,
according to state water regulators.

Last July, Olin Corporation discontinued shipments of bottled water to
roughly 1,200 homes along the edges of a 9.5-mile perchlorate plume
extending southeast from its former Tennant Avenue factory. The move
hinged on water samples showing that the contaminant, which can cause
thyroid dysfunction, had dropped below levels deemed dangerous by state
environmental regulators.

Of the 530-plus wells that no longer triggered requirements for free
water, 21 have since climbed back into the range of concern set by
regulators, according to regulators at the Central Coast Regional Water
Quality Control Board.
